Using nslookup , you should also be able to validate the fully qualified domain name:

Macintosh-7:~ jclarke$ nslookup 172.16.1.12
Server: 11.11.1.250
Address: 11.11.1.250#53
12.1.16.172.in-addr.arpa

name = cm01cel01.

12.1.16.172.in-addr.arpa name = cm01cel01.centroid.com.

Macintosh-7:~ jclarke$

With the terminal emulator of your choice, simply establish an SSH connection to the server that you wish to log
on to. In the example below, we're using ssh from a Mac OSX shell prompt:

Macintosh-7:~ jclarke$ ssh root@cm01dbm01
root@cm01dbm01's password:
Last login: Mon Aug 27 00:15:42 2012 from cm01dbm02
[root@cm01dbm01 ~]#

■ You can use any terminal emulator or shell that supports SSh to log in to the Exadata Compute and
Storage node.

Note

Once logged in, you can manage and administer your system.

■ in addition to gaining shell access via SSh to manage your Exadata servers, you can also access them from
the integrated lights Out Management ( ILOM ) console or KVM console. You can find information about these administrative
interfaces in your Exadata Owner's guide.

Note

How It Works
Each Exadata Compute and Storage Node is configured to run OpenSSH, which you can validate using the service
sshd status command as root:

[root@cm01dbm01 ~]# service sshd status
openssh-daemon (pid 7030) is running...
[root@cm01dbm01 ~]#
